When I was in a company, it looked very bad, that is, the state of an object is represented by Int. Personal perception mainly has the following shortcomings.
Advantages of enumeration:
1. Although int is a strong type in C #, Int Is not a strong
It is a binary-based bitwise operation that is expressed by the symbol XOR or ^.AlgorithmIt is the binary bit of the number on both sides of the operator. Take 0 for the same value and 1 for the same value. It differs from a Boolean operation in
When I first went to the company for a written test a few days ago, I ran into several bitwise operations. I was just reading C ++ primer and happened to see bitwise operations. So I went online to search for the next article. Article To study it!
Our practice is usually (especially in the learning phase): to define a new variable and use it for exchange. The Code is as follows: int A, B;
A = 10; B = 15;
Int T;
T = A; A = B; B = T;
This algorithm is easy to understand and is especially

In an integer array a with a length of n, all the other numbers appear twice except three digits. Write a program to output any number that appears only once. The smaller the time and space complexity of the program,
LeetCode 260 Single Number III (only the Number III appears once )(*)Original
Given a numeric array nums, two elements appear only once, and all other elements appear twice. Find the two elements that appear only once. For example, if nums = [1, 2, 1
Here we implement suchAlgorithm: The addition, subtraction, multiplication, and Division operations are not used. Only bitwise operations are used to add and subtract integers.
Principle: The exclusive or operation also becomes a semi-addition. In
I have encountered an integer that counts the number of 1 in its binary. To put it bluntly, I used recursive calls to divide the remainder by 2 and determine the remainder. If it is 1, Count ++; otherwise, Count remains unchanged. Although the
1/* determine how many digits need to be changed before integer A can be converted to integer B 2 * Identify the differences between two digits, you can use an exclusive or operation to 3 * view the result of an exclusive or operation, each 1
